Application filed January 27, 1913, Serial No. 744,576. Renewed June '20, 1917. Serial No. 175,972.

To all whom it may on ern:

Be it known that I, MATTHEW L. KING, a citizen of the United States, residing at Bradley, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Forms for Masonry Structures, of which the following is a specification.

The object of my invention is to provide a form of simple, durable and inexpensive construction for use in building frames out of plastic material for openings in buildings.

More particularly, it is my object to provide a form for building the door frame and jambs for a continuous opening in a silo wall, in which form door sections or form members of the same size are employed, thereby enabling me to build a frame which exactly fits the silo door sections.

My invention consists in the construction, combination and arrangement of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of a portion of a silo wall showing the door opening with my form installed in position.

Fig. 2 shows a horizontal, sectional view taken on the line 22 of Fig. 1.

Fig. 3 shows a detail, horizontal, sectional I view of portions of my improved form for masonry structures. Fig. 4 shows a detail View of a retaining rod, and

Fig. 5 shows an end view of one side of my improved form for masonry structures without showing the silo or other wall.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally the wall of a building, such as a silo or other structure, which wall is preferably provided with a continuous door opening 11. My form is designed particularly for forming jambs or frames for said door openings which jambs or frames are built to exactlv fit door sections of certain sizes.

My form is composed of the adjacent wall member 10 which may be in the form of wooden stave, cement block, hollow tile or other material. It will be understood that where a hollow block or tile is used, a small amount of the cement will flow into the block or tile. This has the advantage of firmly securing the jamb member which is made of plastic material to the wall.

I employ upright, outer members 12, preferably made of somewhat resilient material, the main body of which is curved in cross section, as shown in Figs. 2 and 3, to correspond with the curve of the outside of a silo wall. At their adjacent edges, the members 12 are extended inwardly with a sharp curve at 1% and then have portions 13 extending toward each other in a plane substantially at right angles to the planes of the portions 14, it being my purpose to form on the outside of the door jambs adjacent curves 15 for receiving fastening devices on doors. The ends of the form members 12 adjacent to the door opening, I shall call the inner ends. Extending from the inner ends of the portions 13 inwardly and away from each other are flat vertical metal form members 16 having portions 17 extending into the open space between the member 16 and the structure wall, for reinforcing purposes. The members 16 and the portions 17 may he ordinary T irons. The members 16 are designed to form a part of the form and also to remain as a permanent part of the door jamb and the outer faces of the member 16 are designed to fit the beveled edge of the door. On the inside of the structure, I provide vertical form members 17 of approximately the same length as the members 12 and designed to constitute the inner wall of the form. The form members 17 are of sufiicient width to overlap the inner part of the wall 10 and extend beyond the members 16 into the door opening. The members 17 may be slightly beveled to fit the other form members hereinafter described. For properly spacing the members 16 apart, I employ a form member 18, which may be an ordinary door section or a form member of substantially the same shape and size. By using the form member 18 of the same shape and size of the door section, I am enabled to space the members 16 apart exactly the proper distance for receiving the door sections when the jamb is completed by the use of my improved form. For holding the inner edges of the form members 16 against spreading, I employ a rod or bar 19 having at its ends hook members 20 designed to engage the inner edges of the form members 16, as shown in Figs. 1, 2 and 3. The rod or bar 19 is preferably somewhat longer than the ordinary distance between the inner edges of the members 16 so that if the form member 18 should vary somewhat in width, the rod 19 may be arranged at an acute angle with relation to the longitudinal axis of the door opening, as shown in Fig. 1 and will still hold the members 16 against spreading.

I preferably secure to the portion 17 of the members 16, a plurality of anchoring devices 21 designed to extend through the masonry door j amb to and into the structure wall 10. In order to further prevent the spreading of the members 16 and to hold them in their proper position, I provide rods 22 having at their ends hook members 23 designed to engage the members 17, as shown in Fig. 2. The rods 22 are designed to be secured just above and just below the form members 12 and against the edges of the member 16 opposite the edges to which the hook members 20 of the rods 19 are secured; For holding the form members 12 and 17 in position, I have provided the following means.

Near each end of the members 12, outside the door opening, I provide a pair of angle irons 24 having one portion in a horizontal plane, and extending outwardly from the form members 12 and having the other portion in a vertical plane and resting against the form members 12. In the vertical member of the angle irons 24 I provide two longitudinally elongated slots 25 designed to be adjacent to the members 12 when the parts are installed in position. The members 17" and 12 are provided with suitable openings which register with each other on each side of the door opening, and extending through the members 17 and 12, and through the opening 25, at each end of the angle bar, is a bolt or rod 26, the outer end of which is screw threaded at 27. On the outer end of each rod 26 is a thumb nut 28. On the rod 26, between the thumb nut 28 and the angle bar 24, I provide suitable collars. 29 and washers 80. On account of the fact that the thickness of the wall 10 may vary in d f ferent silos, the slots 25 are elongated so that the bolts or rods 26 will be received in said slots in all cases. For holding and supporting the members 12 in position, I provide bars 30, the inner ends of which. are designed 'to rest against the outer surfaces of the portions 13 of the form members 12. The bars 3O extend outwardly from the structure wall, adjacent to the horizontal flanges of the angle bar 24. The bars 30* are provided with elongated slots 31 and the horizontal flanges of the angle bar 2 1 are provided with suitable openings in which are received bolts 32 which extend through the slots 31 and are formed with screw threaded ends on which are winged thumb nuts 33. 'It will thus be seen that on account of the elongated slots 31, the bars 30? are adjustable for use with silo walls of varying thicknesses.

In installing my improved form for ma sonry structures for building the jambs or frames of silo or other doors, the members 17" and 12 are placed in horizontal position. The member 12 is of somewhat resilient material so that it may be bent or sprung to conform to the shape of the structurewall regardless of the thickness of the wall 10. The members 16 are placed in upright position and the anchoring or reinforcing devices 21 are secured thereto. The rods 19 are secured in position and the rods 22 mounted in their proper places. I then install the bars 24 and place the bolts 26 in the proper opening. The bars 30 are then secured in position and the door 18 is placed between the mem bers 16. On the outer surface of the form member 18 I secure sliding catch members 35, mounted in guide ways 36 which may be of ordinary. construction. The catch members 3O are preferably mounted in position slightly spaced apart from the member 18, so that when the members are in stalled in position for use, the catch members 35 maybe moved to engage the outer surfaces of the portions 13 of the form member 12, as shown in Fig. 3. If desired, suitable form members may be placed in position for leaving an air space in the plastic material. Nhen the form members are in position at the bottom of the door opening 37, plastic material is poured from the top into the space between the members 12 and 17 the wall and themember 16. The form members, excepting the members 16, the reinforcing rods 21 and the rods 22 are designed to be removed when the plastic material is hardened.

The advantages of my improved formv may be seen from the foregoing description. Es-

pecially, in the building of silo door frames,

where it is desirable to have a door made in sections and to have said sections fit very snugly to make an air tight joint, it is very difficult to build a frame which the door sections will fit against properly. improved form and employing as one of the members thereof, the member 18, made in the shape and form of a door section, the door jamb or frame, when completed, will exactly fit the door sections to be used in the door opening. By using the members 16 having smooth faces, inclined in the positions shown in Figs. 2 and 3 in connection with the member 18, I am able to form a frame having a smooth inclined face suit able to fit the door section, which, especially in silos is installed from the inside. On account of the position of the members 16, the door section will be pressed more tightly to By using my members, and means position by any pressure from the ensilage within the structure.
